ruby - 使用 Ruby 的 Mechanize 登录时遇到问题

Question

尝试创建一个自动登录网页，该网页采用 HTTP POST 输入但未能成功。

这是网页:https://job.jobnet.dk/CV/Login/Login.aspx

如果您想尝试一下，我创建了一个用户 stacktest，密码为 abcdefghijklmn1。

这是无效代码:

require 'rubygems'
require 'mechanize'

agent = Mechanize.new
page = agent.get 'https://job.jobnet.dk/CV/Login/Login.aspx'

login_form = page.form_with(:action => 'Login.aspx')

login_form['ctl00$ctl00$JobnetBaseMiddelContent$LoginContentPlaceHolder$txtUsername'] = 'stacktest'
login_form['ctl00$ctl00$JobnetBaseMiddelContent$LoginContentPlaceHolder$txtPassword'] = 'abcdefghijklmn1'

page = agent.submit login_form

p page # should be a new page but isn't a new page

不用说它不起作用:)

还有一个名为__VIEWSTATE 的隐藏输入字段，其值为

试试这个:

require 'rubygems'
require 'mechanize'
require 'pp'

user = 'stacktest'
password = 'abcdefghijklmn1'

agent = Mechanize.new
page = agent.get 'https://job.jobnet.dk/CV/Login/Login.aspx'


form = page.form_with(:action => 'Login.aspx')
form.field_with(:name => "ctl00$ctl00$JobnetBaseMiddelContent$LoginContentPlaceHolder$txtUsername").value = user
form.field_with(:name => "ctl00$ctl00$JobnetBaseMiddelContent$LoginContentPlaceHolder$txtPassword").value = password
page = form.click_button

pp page
